0x0D0B
[7]
Frequency clamped
The upper or lower frequency tuning word clamp is in effect.
[6]
History available
There is sufficient tuning word history available for holdover operation.
[5:3]
Active reference
priority
Priority value of the currently active reference.
000 = highest priority.
111 = lowest priority.
[2:0]
Active reference
Index of the currently active reference.
000 = Reference A.
001 = Reference AA.
010 = Reference B.
011 = Reference BB.
100 = Reference C.
101 = Reference CC.
110 = Reference D.
111 = Reference DD.

Description
0x0D0C
[7]
Profile selected
The control logic sets this bit when it assigns Ref A to one of the eight profiles.
[6:4]
Selected profile
The index (0 to 7) of the profile assigned to Ref A.
Note that these bits are meaningless unless Bit 7 = 1.
[3]
Valid
Ref A is valid for use (it is unfaulted and its validation timer has expired).
[2]
Fault
Ref A is not valid for use.
[1]
Fast
If Bit 7 = 1, then this bit indicates that the frequency of Ref A is higher than allowed
by its profile settings.
If Bit 7 = 0, then this bit indicates that the frequency of Ref A is above the maximum
input reference frequency supported by the device.
[0]
Slow
If Bit 7 = 1, then this bit indicates that the frequency of Ref A is lower than allowed by
its profile settings.
If Bit 7 = 0, then this bit indicates that the frequency of Ref A is below the minimum
input reference frequency supported by the device.
0x0D0D
[7:0]
Same as 0D0C but for REF AA instead of REF A.
0x0D0E
[7:0]
Same as 0D0C but for REF B instead of REF A.
0x 0D0F
[7:0]
Same as 0D0C but for REF BB instead of REF A.
0x0D10
[7:0]
Same as 0D0C but for REF C instead of REF A.
0x0D11
[7:0]
Same as 0D0C but for REF CC instead of REF A.
0x0D12
[7:0]
Same as 0D0C but for REF D instead of REF A.
0x0D13
[7:0]
Same as 0D0C but for REF DD instead of REF A.
